Area of ABCD  =  300 cm²

Step-by-step explanation:

Let say side of Square =  a cm

Then AC = BD = a cm

AB = CD = 3a cm

Perimeter = 2( a + 3a)  = 8a

8a = 80 cm

=> a = 10 cm

AC = BD = 10 cm

AB = CD = 30 cm

Area of ABCD  = 10 * 30  = 300 cm²

or area of each square = 10 * 10 = 100 cm²

area of figure by 3 Squares = 3 * 100 = 300 cm²

Area of ABCD  =  300 cm²
